Wing Koriboh cards

Have the Game Boy Advance game Yu-Gi-Oh! GX: Duel Academy in the cartridge slot to start with three Wing Koriboh cards.

Getting desired cards

While you are in the house, save the game. Go to the store and make sure you have enough money to buy a pack of cards. If the card you want is not in the pack, turn of the DS. Turn the game back on and you will be back at the house. Go back to the store and you will still have all your money. Repeat this until getting the desired card.

Registering as a duelist

After defeating a Duelist eight times, he or she will ask you if they can register you as a Duelist. If you say "Yes", you can choose whether or not you want to play them the next time you encounter them.

Easy KC and experience

Duel Tea Gardner as many times as possible until she asks to be your friend. Answer "Yes" and you will be able to duel her non stop until evening. To get more KC and experience, try this with other feeble or weak characters, such as Serenity and Mokuba.

Never duel difficult duelists

All the easy duelists are out in the daytime. When it turns to evening, walk to your house and go to the shop. Do this until it turns to night. Go to your house and sleep. It will be morning again and you can duel easier duelists once again.

Winning at Rock, Paper, Scissors

When dueling against an opponent and you do Rock, Paper, Scissors, remember what you did in a previous duel and use the one that can defeat what you used last time.

On the card Deck Destruction Virus, it shows the picture and description of Deck Devastation Virus and vice-versa. However, when they are played they use the effect of the card named at the top of the screen.

Aqua Chorus card mistake

If you look at the name of the Aqua Chorus card carefully, it reads "Blue-Eyes White Dragon" on the card instead of "Aqua Chorus".

Blue Medicine card mistake

The description of the Blue Medicine card reads that both you and your opponent gain 400 LP; however after the card is played only you gain 400 LP.

Sage's Stone card mistake

The description of the Sage's Stone card reads "Sage's Jewel", but on the actual card itself it has the correct name.

Misspelling

At the Duel Base, Roland says "Duerist" instead of "Duelist".
